A resident using a bronchodilator inhaler should be advised to?

Using a bronchodilator inhaler correctly is crucial for effective treatment of respiratory conditions. Advising a resident to use the inhaler no more frequently than it is ordered is essential because overuse can lead to increased side effects and potential complications, such as an increase in heart rate or anxiety. It's important for the resident to adhere to prescribed dosages to ensure both the safety and effectiveness of the medication.

The other options suggest practices that could hinder the inhaler's effectiveness. For instance, inhaling in short shallow breaths would not allow for adequate delivery of the medication deep into the lungs. Similarly, exhaling rapidly or using the inhaler with oxygen are not appropriate practices that could result in improper medication absorption or effectiveness.

Thus, promoting adherence to the prescribed frequency helps facilitate proper management of the resident's respiratory condition.
